To all 2071 om it may concern:

Henderson, in the countyof York and State of Nebraska, have invented new and useful Improvements in. GraiirMeasuring Devices,

oi which the following is a specification. I

This invention relates to improvements in measuring devices especially adapted for use in connection with threshingmachines :tor the purpose of measuring grain.

An object of the present invention is the provision of means. for measuring the threshed grain so that the amount will not *ary irrespective of the condition of the grain, means being provided whereby the measure may be adjusted to regulate its capacity.

Another object of the invention is the provision of means which may be attached to the threshing machine and operated and controlled by the mechanism of thelatter to continually measure thegrain as it is being threshe V 7 Another object of the invention is the provision of means for automatically ele-' vating the grain '.within thefilled measure so that the amount will be the same at each operation. I a Y 1 Another object of the invention is the provision of a measuring device which in-* cludes a plurality of measures or compartments which are alternately filled and dumped, automatically operated means being provided for releasing the contents: of V a filled measure or compartmentand closing the other measure or compartment for filling. i i. With the above and other objects-in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illus trated in the accompanying drawings and pointed out in the appended claims.

In the drawings i Figure -1 is a fragmentary side elevation showing a portion of the conveyor housing of a threshing machine with the invention applied. V Figure 2 is a similar view looking at the side opposite that shown in Figure l.

p taken substantially on the-line 4-41 of Fig Be it known that I, FRANK F. DICK, a; i citizen of the United States, residing at ure1.; F gure 5 s an enlarged horizontal sec.-

tional view taken substantially on the line 5+5ofFigurer1. 1 v i Figure is a detail perspective view of one of thepivoted bottoms of the measuring compartments. 7 1

Figure? .is a detail perspective view of one of the stop lugs. I i l R ferring. to -th -e drawings in detail wherein. like charactersojf reference denote corresponding parts, the reference character 10 indicates a portion otthe housingof a threshing machine conveyor. This conveyor may be of the usual or any desired type and p is shown as comprisingan endless belt 11 which carries a plurality of ,buckets 12.

The belt passes over air-pulley 13 which. is mounted upon a shaft l iextending transversely through the upper end of the;houstioned for horizontal swinging movement beneath the chute 15. The bin is further: I

divided into separate measuring compartcludes an upper'stationary section and a ing 10 and arrangedyso that the bucketslQ i will discharge the grain laterally for, passage through ments 19 by means of a partition 20. This :partition is ofnovel construction and .in-

lower movable section. This last mentioned;

section comprises apair of relatively movable panels 21 which are pivotallytmounted as shown at 22 and which may beadjusted laterally to regulate the capacity of each measuring compartment. The panels 21 are held in adjusted position by-means of set screws 23 which are carried by the bin or container 18 and wh ch passes through slotted arcuate arms 24 securedto each of the panels 21. The bottom of each measuring compartment 19. is. formed bya'gate or closure 25 which is pivotally mounted as shown at 26 and which provides a dump bottom. The bottoms '25 of the compart ments 19 are alternately opened and closed through the pivotal movement of the. con

- tainer :18 andfor the purpose of controlling these bottoms they are each provided with a crank arm 27 whiohis rigid therewith;

These crank arms have an adjustable pivotal connection with links 28 and the latter are in turn pivotally connected to one end of a cam lever 29. The levers 29 are provided near their lower ends with inclined. cam edges 30which engage rollers 31 carried by the container 18. The levers 29 are movable behind guides32 and are pivotally connected as shown at 33 with the outer ends of bell crank levers 34. The levers 34 are pivotally mounted upon the container 18 as shown at 35 and have their opposlte or inner ends adapted for engagement 7 by keeper lugs 36-which are horizontally adjustable along oppositely extending arms 37 which project from the brackets 17. The lugs 36 are held iii-adjusted position by means of setscrews 38 which pass through slots provided in the arms 37 andwhich engage the lugs 36. The camlevers 29 have connected thereto the'lo'wer ends of coiled springs 39 while the opposite ends of these springs are connected to lugs '40 which are secured to the container 18.

hen the container 18 is rocked upon the pivot 16 in a manner to be hereinafter explained, it will be seen by reference to Figure l that a rocking movement of the containerto the right; of said figure will release and open the dump bottom of the right hand measuring compartment 19, while the bottom of the other measuring compartn'ient will be closed and locked in closed" position. \Vhen the container 18 rocked in an opposite direction, the cam edge of the lever 29 at the rigl' tof said Figural will engage the roller 31 so'as to force the link28 outward and close the --door 25, the spring 39 -acting to move the cam lever 29 upward to'the position occupied by the cam lever 29 a-t the left of the said figure. This will cause an extensionll at the lower extremity ofthe levers'29 to engage the roller 31 so that the bottom 25 will be securely held in closed "position, the spring 39 acting toefiect a quick closing of the bottom. Atthesame timepivotal movement of the, container 18' to the left will cause the inner end of the bell crank lever 34 at the left of said figure to engage its particular lug 36 and the latter will act to'move the bell crank lever 34: upon its pivot and force the cam lever 29 down ward souas to open the bottom of the left hand measuring compartment.

Pivotally secured to the container 18 as shown at 42 is one end of a {shifter rod 43'. The opposite end of thisrod is pivotally connected as shown at .44 to the outer end ofa crank arm 45 which is secured upon one end of a'shaft 4L6 extending transversely v (Du-e end of the through the housing .10. shaft has secured thereon a pinion 4:7 which engages and drives a gear 48, the latter being securedupon a stub shaft 63.

'70 means of a chain 71. 1s, adaptedto operatea counter or tally Secured upon the opposite end of the shaft I leis a sprocket tt) over which passes a drive chain 50, the latter receiving power from any suitable source which may be the usual conveyor operating mechanism.

Eccentrically secured to the gear 48 is one end of a connecting bar 51 whose opposite end is secured to one arm 52 0f a yoke, the, securing means being indicated at 53.

which thearm"52 is connect-ed is mounted in: a movable" bearing 57' which is carried at the outer fend'of asubstantially Z-shaped member-5S. One end of this member is slidingly mounted in a bearing arm 59 secured to the housing lOwhile the opposite end of the arm 58 1S slidingly mounted in a bearing 60 also carried by the housing 10.

This end of themember 58 provides a stop. armwvhic-h is located in the path of apair .of diametrically opposite lugs 61 which are secured' to the rear face of a gear 62. This gear is. mounted upon one end of the shaft 46 wvhich extends from the housing 10 and is provided with diametrically oppositeinterrupted portions64 in its toothed face so that 1t may be alternately engaged and disengaged by the pinion 4:7.

The arms 52-and 56 extend downwardly within pockets 65 provided upon opposite sidcsof the housing: 10 and through arcuate slots 66 provided in said housing and are connected a plate 67 which provides a amb plate aswill be hereinafter-apparent.

The .Z-shaped member58 has connected thereto one end ofia spring 67 and the opposits end ofth ls spring isconnectedtothe housing-as shown at 68- so that the member.

58 normally retractedto-hold its inner end In the path of the stop lug 61.

The shaft 46 has "mounted thereon a sprocket 69. which isconnected to a sprocket This sprocket mechanism of any desired type which is located within acas1ng72 carried byv the housing 10. e

Assuming that the container or bin 18 is in the, position shown in the drawings and the-bottoms 25 have been operated in the: manner previously described to close the left hand compartment and open thev right handcompartment inFigure 3 of the drawings, the grain discharged from the buckets 12' will through centrifugal force be directed outward through the chute 15 into: the left-hand compartment '19. As the compartment is being filled, thejamb plate 67 will move; alternately backward and forward across-the chute due to the connection of its yoke with thegear 48. The pinion 47 drives the gear as, but by referenceto F i-gure 2 of the drawingsit will be seen that this pinion occupies one of the interrupted portions of the gear 62so that no motion is imparted to this last mentioned gear and the latter is heldstationa-ry bythe inner end of the Z-shapedmember 58; As soon as the left hand measuring compartment end of the arm. 52 of the yoke is changed substantially to the position shown by the dotted lines in Figure 2. The Z-shaped member 58 is thus moved outward so that the inner end of the said member is moved out of the path; of the stop lug 61. At this juncture, the spring 39 of thecam lever 29 atthe right of Figure 1 of the drawings will d aw this lever 39 upward so that the inner end of the bell crank lever 34 will be forcedca-gainst its lug'36 and as the pivotal connection 44L between the shifter rod 43 and the crank arm 45 is slightly on center, sufiicient movement will be imparted to the shaft 46 to bring the teeth of the gear 62 into mesh with the pinion 47 so that the gear 62 will be rotated one-half revolution or until the opposite interrupted portion of the teeth will cause the disengagement of the gear 62 and the pinion 47. At this point the opposite stop 61 will engage the inner end of the member 58 which has been previously moved into the path of the stop through the inward movement of the yoke under the action of the connecting bar 51 and the spring 67.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims. 7
